22 Claims.

This invention relates to lasting machines, and more particularly tomachines of that type that pull an upper by means oi a grippersuccessively in diiierent locations along the edge of the shoe bottomand fasten the upperafter each upperpulling operation. The invention isherein illustrated as applied to a machine the general organisation ofwhich is substantially as disclosed in Letters Patent No. 1,796,451,vgranted on March 17, 1931 upon an application of George Goddu,Y

the machine having means for driving staples to fasten the upper to alip on an insole or sole (hereinafter referred to generically' as thesole) and means for clinching the staples on the lip.

- It is to be understood, however, that the invention is not limited toan organization offthatv particular character, nor to machines thatfasten the upper to a lip; and it is also to be understood that it isnot limited to machines that drive staples or other fastenings, but isapplicable, for example, to machines in which the fastening means simplypresses the marginal portion of the upper into position to adhere to thesole without the insertion of any fastening.

Machines of the character illustrated in the above-mentioned LettersPatent are now. commonly so constructed that they gripper operates onthe upper` in a location spaced somewhat lengthwise of the edge of theshoe bottom from the location where the upper-fastening means operateson the shoe; i. e., in a location at the left of that where thefastening is inserted, considered with reference to the operatorsworking position in front oi the machine. It is therefore necessary thatthe operator move the shoe from left to right in the progressive lastingof each of its opposite sides, so that the lasting operation progresses`toward the toe end of the shoe along one side of the shoe and toward theheel end along the other side.

The present invention providesv a construction such that if conditionsshould render it desirable both sides of a shoe may be lastedprogressively toward the same end thereof; for example, toward the heelend. For this purpose the gripper, in the embodiment of the inventionherein illustrated, is so mounted and controlled that it is shiftable atthe will of the operator toV carry the upper-engaginfr portions of itsjaws lengthwise of the edge ci the shoe bottom past the location offastening insertion and thus to position the jaws for operation on theupper at either side of that location selectively. This permits the shoeto be moved in opposite directions in lastingits opposite sidesrespectively, so that the lasting may begin, for example, near the toe`end and mayy progress toward the heel end at each side. Novel mechanismis provided to enable the operator to shift the gripper quickly from oneoperating position to the other; and there are further provided novelmeans for maintaining the gripper in each operating position and forinsuring against such damage to the machine as might result from itsaccidental displacement fromeither position.

The above and other features ofthe invention, including various noveldetails of construction and combinations of parts, will now be moreparticularly described by reference to the accompanying drawings andpointed out in the claims.

In view of the disclosure of the above-mentioned Letters Patent, onlysuch parts of the general organization of the machineas it is necessaryto consider for an understanding of rthe present invention will behereinafter referred to. For pulling an upper successively in differentlocations along the edge of the shoe bottom as the shoe and last arepresented by the operator in different positions, the machine isprovided with a gripper comprising a pair of jaws I0. and I2, the jaw I0being fast on a holder I4 having an upwardly extending tubular shankportion I6. The jaw I 24 is supported on the holder I4 for swingingmovements toward and from the jaw. I0 to grip and release the upper,such movements being impartedv thereto through a rod I8 slidinglymounted in the holder and in itsv shank portion I6. The gripper is movedheightwise of the last to pull the upper by an updraw lever 20, con-`nected to the shank portion I6 in a manner hereinafter described, thislever being operated by a power-driven cam on a cam shaft 22. As thegripper is moved downwardly by the lever 20 into position to grip theupper and is thereafter moved upwardly by the lever to pull the upper,the tubular shank portion I6 slides in a bearing provided in a guideblock 24 connected as hereinafter described to a horizontal overdraw rod26 by forward movement of which the gripper is swung forwardly towardthe operator, in time relation to its upper-pulling movement heightwiseof the last, to pull the marginal portion of the upper inwardly over thebottom of the last, and by rearward movement of which the gripper jawsare carried toward the edge of the shoe bottom preparatory to thegripping of the upper. For laying the marginal portion of the upper overand upon a sole on the last in time relation to each upper-pullingoperation of the gripper the machine is further provided with anoverlaying member 28 movable toward the shoe in a forwardly anddownwardly inclined direction. This member in the machine herein showncomprises a nozzle from which a staple S (Figs. 6 and 7) is driven by astaple driver 30 to fasten the upper to the sole at the end of eachoverlaying operation. As herein illustrated, the staple is driventhrough the upper and through a lip on the sole, and its legs areclinched on the lip by an'anvil 32 which engages the inner face of thelip and serves to position the shoe heightwise and laterally. As thusfar described, the construction of the machine and the manner in whichit operates, except as hereinafter noted, are substantially as disclosedin the previously mentioned Letters Patent.

To permit the gripper to be swung forwardly to pull the upper inwardlyover the bottom of the last by forward movement of the overdraw rod 26as above described, and also to permit it to be swung laterally, i. e.,in directions lengthwise of the edge of the shoe bottom, for purposes ofthe present invention, it is connected to the updraw lever 20 by themeans illustrated in Fig. 5. The shank portion I6 of the holder I4 isheld at its upper end by a clamp 34 having an upwardly extending annularportion 36 from opposite sides of which project trunnions 38. One of thetrunnions 38 is mounted in a bearing in a lug 40 which is part of amember 42, and the other trunnion is mounted in a bearing in a lug 44provided with a pin 46 that projects through an opening in the member 42and is threaded to receive a nut 48 which holds the lug 44 fast on themember 42. The member 42 has projecting therefrom a stem 50 whichextends at right angles to the trunnions 38 and is mounted to turn in abearing in the forward end of the updraw lever 28. A nut 52 on the stem58 holds the member 42 in place on the updraw lever. It will thus beseen that the gripper may be swung forwardly about the axis of the stem50 to pull the upper inwardly over the bottom of the last and may alsobe swung laterally about the axis of the alined trunnions 38 to carrythe gripper jaws in directions lengthwise of the edge of the shoebottom.

' Swinging movements of the gripper about both the above-mentioned axesare effected by movements of the guide block 24 which is connected tothe overdraw rod 26 as will now be described. The overdraw rod has avertically attened front end portion 54 (Fig. 2), and projectinglaterally of the gripper from one side of this flattened portion of theoverdraw rod is a short bar 56 which has aV reduced threaded end 58extending through the flattened portion of the overdraw rod and securedthereto by a nut 60. Mounted on the bar 56 to slide lengthwise thereofand also to turn thereon is a member 62 (Fig. 3) that is swiveled in theguide block 24, this member having a cylindrical portion 54 that engagesperipherally arc-shaped upper and lower bearing faces formed in a recessin the guide block. At both sides of this cylindrical portion 64 the bar56 projects through openings in the sides of the guide block 24 whichare enough larger than the bar to permit the guide block to turnrelatively to the bar as required in the lateral swinging movements ofthe gripper about the axis of the trunnions 38, as will be evident byreference to Fig. l. The member 62 is further provided with upper andYlower flanges 66 extending beyond the periphery of the cylindricalportion 64 and havg ing arcuate faces engaging corresponding bearingfaces formed on the block 24. The block 24 and the member 62 are held inassembled relation to each other by a plate 68 secured by cap screws'IIJ to the block 24 in overlapping relation to the flanges 66. It .willthus be seen that the member 62 serves to connect the guide block 24 tothe bar 56 in such manner that the gripper is swung in oppositedirections by forward and rearward movements of the overdraw rod 26, themember 62 turning on the bar 56 in these movements.

The swinging of the gripper laterally, i. e., in directions lengthwiseof the edge of the shoe bottom, for the purpose hereinbefore describedis effected by rectilinear sliding movements of the member 62 along thebar 56. For this purpose the member 62 has projecting forwardlytherefrom through an opening in the plate 68 two lugs 'I2 (Figs. 2 and3) which have arcuate outer faces engaging a corresponding edge face ofthe plate 68 and vertically straight inner faces between which islocated a roll 14 (Fig. 3). This roll is mounted on a crank pin carriedby a forwardly and rearwardly extending shaft 'I6 which is rotatable ina bearing formed in a bracket 'I8 secured to the forward end of theoverdraw rod 26 by screws (Fig. 2). The roll 14 thus serves as aneccentric member in front of the gripper for swinging the gripperlaterally by movement of the member 62. A reduced portion of the shaftI6 extends through a plate 82 secured to the bracket I8 and has on itsforward end a collar 84 engaging the plate 82 to hold the shaft againstlengthwise rearward movement, its forward movement being prevented byengagement of a flange 85 thereon with the bracket 18. Formed on theshaft 'I6 are gear teeth 86 which constitute a pinion integral with theshaft and engaged by the teeth of a gear sector 88 movable in a recessbehind the plate 82. This gear sector is part of a member 90 rotatablymounted on a forwardly and rearwardly extending pin 92 which is securedto the bracket 18, the member 90 being forked so that portions thereofare supported on the pin 92 at opposite sides of an ear 94 on thebracket. Extending from the member 90 is a hand lever 96 by which themember may be turned by the operator at will to turn the shaft 'I6 andthereby swing the gripper in such manner as to carry its jaws in onedirection or the other past the anvil 32 and the location of fasteninginsertion to position them for operation on the upper at either side ofthat location. A pin 98 projecting from the bracket 'I8 into a slot inthe member 90 Serves to limit mevements of the member in oppositedirections and thus to determine the diiferent positions of the gripper.VIt will be evident that the relation of the eccentric roll '(4 to themember 02 is such as to permit the turning mo-vements of this member onthe bar 5'6 that necessarily occur in the forward and rearward movementsof the overdraw rod 20.

Mechanism is further provided for maintaining the gripper yieldingly ineither position to which it is swung by movement of the means abovedescribed, so that during the pull on the upper its jaws are positionedat a substantially xed distance lengthwise o f the edge of the shoebottom from the location of fastening insertion. This mechanismcomprises a member |00 which is fast on a rockshaft |02 mounted to turnin a bearing in the bracket 18, the member |00 having therein a plunger|04 which is pressed downwardly by e Spring |06 and .has .e roundedprojection |08 seated in a correspondingrecess in an arm ||0 that isDalit of the member 90. A

collar 2 (Fig. 3) on the rockshaft |02 holds the shaft against forwardmovement in its bearing. By reference to Fig. 2 it will be evident that,as the parts are there positioned, the plunger |04 by its action on thearm ||0 serves to retain the member 90 and the gripper yieldingly in thepositions indicated, since the force exerted on the arm ||0 by theplunger |04 is along a line at the right-hand side of the axis ofmovement of the member 90. When the member 90 is turned to move thegripper to the other position determined by the pin 98, the arm ||0 byits action on the plunger |04 causes the member |00 .to turn with theshaft |02 to a position in which the force of the plunger is directedalong aline at the left-hand side of the axis of the member 90 andtherefore serves to maintain this member yieldingly in that position.Accordingly the arm ||0 and the spring-pressed plunger |04 comprisetoggle-like members which serve to maintain the gripper yieldingly ineither of the positions to which it is swung by the hand lever 96.

It is important that in each cycle of the machine the gripper jaws shallbe so positioned as to operate either at one side or at the other sideof the anvil 32, since if they should occupy an intermediate positionthey would strike the anvil in their rearward movement to grip the upperand parts of the machine would be broken. Mechanism is accordinglyfurther provided for insuring against such damage to the machine. Forthis purpose one of the arms of the previously mentioned forked portionof the member 90 has thereon an upwardly extending lug |4 (Fig. 2) towhich is fastened a member HG having a V-shaped upper edge portion.Arranged to cooperate with this member is a slide IIB having a V-shapedlower edge portion, this slide being vertically movable in a guidewayformed in an upward extension of the bracket 18. Fastened to the slideI8 is a member |23 connected by a link |22 to a lever |24 (Fig. 1) whichis mounted for swinging movements in a vertical plane and extendsrearwardly to a position over the cam shaft 22. At its rear end thelever |24 carries a screw |26 which rests on the upper end of a slide|28 (Fig. 4) guided for vertical movements in the frame of the machine.The slide |28 at its llower end carries a roll |30 engaged by a cam disk|32 on the cam shaft 22. This cam disk has therein a depression |34(Fig. 1) in which the roll |30 lies when the parts of the machine are intheir starting peeitiens- .A Spring-1.3.8 eeeeeied to the rear end ofthe lever |24 tends to pull this end of the lever downwardly and thusholds the roll |30 at all times in engagement with the cam disk |32.Immediately upon the starting of the machine the cam disk serves toraise the slide |28 and thereby to swing the lever |24 in the directionto move the slide I8 (Fig. 2) downwardly along its guideway. If,therefore, the gripper s119111@ be accidentally positioned at this time.between the limits of its opposite lateral swinging movements, so thatits jaws might strike the anvil 32, the lower V-shaped portion of theslide ||8 engages the corresponding upper portion of y the member H0 atone side or the other of the latter and thereby imparts to the membersuch movement that the gripper jawsare carried to one or the other oftheir normal starting positions before they receive their rearwardmovements to seize the upper.

In order to permit the gripperjaws to be swung laterally past theclinching anvil as above described, the anvil 32 herein shown isconstructed and mounted somewhat differently than in earlier machines ofthe illustrated type. The anvil 32 is formed from a plate of springsteel and is adjustably secured to a rod |38 (Figs. 1 and v8) which isclamped in a split bearing formed in a bracket |40, this being thebracket on which the anvil has been supported heretofore. The anvil ismounted in an opening formed in one side of the rod |38 and is providedwith beveled edges one of which extends into a corresponding recess inthe rod and the other of which is Vengaged by a clamp member |42 held bya washer |44 and a screw |46 on the end'of the rod. `It will f3.

the staple-guiding member 28 by turning the rod l |38 in its bearing inthe bracket |40. Since the anvil is made of spring steel, it /mayyieldvto accommodate itself to different thicknesses of Ashoe materialsclamped between it and the member 28. By reference to Fig. 1 it will beevident that the anvil is so formed and mounted as to afford clearancefor the gripper jaws as the jaws are swung past it in one direction orthe other when the 'parts of the machine are in their startingpositions.

Figs. 6 and '7 illustrate how the machine, oonstructed as described, maybe used in lasting the opposite sides of a shoe. In Fig. 6 the gripperjaws are so positioned as to operate at the righthand side of thelocation of fastening insertion, and accordingly the operator moves theshoe from right to left to present it successively in differentpositions for lasting, the lasting operation progressing as illustratedfrom the toe portion of the shoe toward the heel portion. To permit thelasting voperation to progress from the toe portion toward the heelportion also in lasting `the other side of the shoe, the gripper jaws inFig. 7 are positioned to operate at the left-hand side of the locationof fastening insertion so that the shoe may be moved from left to right.It will be evident that by the mechanism described theoperator isenabled to effect a practically instantaneous shifting of the gripperfrom one position to the other to accomplish the objects in view. theoperator'desires to use the machine in the same manner as machines ofthe illustrated type have been used heretofore, he may leave the gripperjaws positioned as illustratedin Fig. 'l and operate on both sides ofthe shoe with the jaws in that position.
